Welcome!

What is an SIC / NAICS Industry Code?

The Standard Industrical Classification (SIC) and the North American Industry Classification System (NAICS) codes are used to identify the type of business in which a company is engaged. Many companies have more than one industry code. A variety of agencies and business sources use these codes to gather statatics and group like companies.

Standard Industrial Classification (SIC)

SIC is a 4 digit system used to define & classify businesses by their type of activity.  SIC was replaced in 1997 by North American Industry Classification System (NAICS).  Some business and resources still use SIC information.

1st   2 digits indicate the general industry group 

              58  (Eating & Drinking Places)

              59   (Miscellaneous Retail)

2nd  2 digits specify a more focused industry segment  12 or 63

              5812 – Coffee Shops

              5963 – Coffee Cart-Food Service – Retail

North American Industry Classification System (NAICS)

NAICS was first released in 1997, the system uses 6 digits.  This allows for a more detailed classification system.  NAICS is releasing updates to the classification system during 2012.  Some codes will be consolidated while others will be moved to another code.
